Application led January 11, 1906. Serial No. 295,615.

.To all whom it may concern:

Be it known that L'JOHN C. GEBHART, a

at Atlantahin the county'of Fulton and tate of Georgla, have invented a new and useful Relverslng Turbine-Engine, of which tlie following is a specification. This invention relates to rotary engines, and has for one of its objects to provide an engine which may be quickly reversed and which is equally effective in both directions of movement.

A further object of the inventionis to rovide a novel form of' rotary engine in w 'ch both the impact and pressure of the operating Huid may be utilized to the fullest advantage. I Q

A still further object of the invention is to provide a rotary engine in which the piston wing or member on which the fluid acts is formed or carried by two adjacent revoluble members so connected that successive wings will be formed and presented opposite the inlet-port as said members revolve.

With these and other objects in view, as will more full hereinafter appear, the invention consists n certain novel features of construction and arrangement of parts hereinafter fully described, lllustrated in the accompanying drawings, and out in the appended claims, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advanta es of the invention.

n the accompanyin drawings, Figure 1 is a sectional elevation o a rotary englne constructed in accordance with thev invention. Fig. 2 is a transverse sectional viewof the same on the line 2 2 of Fig. 1. Fig. 3 is a front elevation of the eno'ine.

Similar numerals of Areference are employed to indicatef correspondin parts throughout the several figures of the drawings.

The main cylinder 10 is provided with a pair of movable end members or heads 11 and 12, and the main section 10 of the cylinder is divided into two chambers by a transversely-disposed partition4 15.

The partition 15 and removable heads 11 and 12 carry bearings for four shafts 17, 18, 19, and 20, the axes of which are arran ed at the four angles of a perfect square. hese particularly pointedl shafts carry ears 21, all of said gears bein of precisely t e same construction and sai gears intermeshing for the purpose of maintaining the pistons of the engine in proper relative posltions and in order to transmit the power to one of the shafts, said shaft 19 being shown as extending through the head 12, and from this shaft motion may be transripherally-disposed wings 31, that are separated from each other Vbypockets of the pecul- 1ar form shown, said pockets being constructed to permit the exposure of the greatest posfluid under pressurewithout waste in the quantity of fluid admitted. The wings 31` are maintained in proper relative position by the gears and are so arranged that two wings will come into engagement with each other and form a continuous wing extending directly across the-pressure inlet-port, so that none of the pressure or' the impact of the entering fluid willl be wasted.

At the center of the several istons is a valve-chamber 33, that preferably forms an integral part of the partition 15. The outer face of this valve-chamber is arra v ed on curved lines'struck from. the axes of t e several shafts and is arranged to form fluidproof joints in connection -with theperipheries of the pistons which move over such surfaces.

Leading from the center to the outside of the valve-casing are two sets of ports 39 and 40, the ports 39 being diametrically opposed to each other and being arranged to permlt the passage of jets of fluld under pressure in a horizontal direction between the several' piston-drums. The ports 40 are diametrically opposed `in a vertical plane and are arranged to direct jets of Huid under pressure 1n a vertical line between the several piston-drums.

Within the valve-casing is arranged a conical valve 41, havin a pair of ports 42, which may be turned to al ow the actuating fluid to pass .through the ports 39 or the ports 40, 1n accordance with the direction in which the engine is to rotate, or the ports may be blanked, as shown in Fig. 1, in order to stop the engine.

slble area ofthe wings to the action of the` IOO Leading through t e removable head 11 is an inlet.- ort 44, the lower portion of which surroun s the outer portion of the valve 41,'

and the latter i's provided with ports 45 in order to permit the free entrance of steam to the interior of the valve at all times. The valve is held in lace by a gland 46, which may be tightened by suitable bolts 47 in order to com ensatefor wear of the valve and prevent lea age. From the outer end of the valve extends a stem 49, to which is connected a controlling-lever 50, and by turning this lever the 'engine may be started in either direction or maybe stopped.

I claim- 1. In a' rotary engine, four piston-d rums,

the peripheries of which are provided with piston-wings arranged to en age each other, a steam-chest arranged at t e centerof the 'series of drums, ports leading from the chest on lines tangential to the drums, and a valve for controlling the flow of steam through said ports.

2. The combination in a rotary engine, of four piston-drums, gears connecting said drums in a continuous series, the peripheries of .the drums being provided wlth pistonwings arranged to engage each other, a steamchest arranged at the center of the series of drums, ports leading from the chest on lines tan' entlal to the drums, and a valve for control ing the flow of steam through said ports.

3. In a rotary engine, four connected and contacting piston-drums provided with peripherally-disposed Wings, andmeans at the center of the series of drums for directing jets of fluid under pressure between them.

4. In a rotary en ine, four connected and contacting drums posed wings, a steam-chest arranged at the aving peripherally-dis- 'center of the series of drums, ports leading from the steam-,chest for directing jets of fluid under pressure between said drums, and a valve for controlling the active ports and thus determining the direction of movement of the engine. v

5. In a rotary engine, four connected and contacting drums aving peripherally-disposed wings, a steam-chest arranged at the center of the series of drums, and theouter surface of which is arran ed on curved lines to follow closely the perip eries of the drums, there being ports leading from the chest outward on lines tangential to the several drums., and an adjustable Valve arranged Within the chest for determining the active ports.

6. The combination in a rotary engine, of four connected and contacting piston-drums having peripherally-disposed wings, a steamchest arranged at the center `of the series of drums and having ports on lines tan ential to said drums, and curved filling-b ocks ar-l ranged to engage With the peripheries of the exhaust sides of the drums.

7. The combination in a rotary engine, of

a cylinder having an approximately central partition and provided With removable heads, a series of four equidistantly-disposed shafts extending through the partition, a pistondrum mounted on each shaft, the peripheries of the drums being arranged to engage each other, ygears arranged at the opposite ends of the shaft and intermeshing in a continuous train, one of said shafts being extended for the purpose of transmit-ting power, a valved and ported steam-chest arranged at the center of the series of piston-drums, and fillingblocks carried by the artition and arranged to engage the peripherles of the exhaust sides of the drums. j
